Definition of diagrid in English:

noun

Within the principal diagrid established by the 36 steel columns that spiral around building (which form an independent self-bracing structure), each floor level is broken down into 72 five-degree modules.

Because of the inherent stiffness of the external diagrid, the central core is required to act only as a load-bearing element and is free from diagonal bracing, producing more flexible floor plates.

Ends of the shell are stiffened with laminated timber arches braced by a diagrid of tension cables from which hang enclosing cardboard honeycomb panels.
